Description
Technical field
The present invention relates to resin wheel technical fields, and in particular to a kind of cymbal type resin wheel and preparation method thereof.
Background technique
Cymbal type resin wheel has extensively in industries such as building, automobile manufacture, shipbuilding, space flight machining and hardware manufactures
General application is mainly used for the processing such as the roughness of crator and working surface on workpiece surface is polished, polished.With society
The industrialized accelerated development of meeting, the aggravation of market competition, raising and user the mentioning for product requirement of wage for workmen's treatment
Height, under the influence of these statuses, the defect of the existing cymbal type resin wheel of industry and insufficient more prominent is mainly reflected in these
Aspect:
(1) cymbal abrasive wheel used in existing market is generally used Brown Alundum and other corundum abrasive systems compared with coarseness
At although abrasive grain is thicker, sharpness is better, and polishing scratch and vibration force also can be bigger, causes workpiece surface after grinding
Roughness and flatness are deteriorated, while comfortable feel degree can decline when product is used and operated.
(2) if the abrasive material that cymbal type resin wheel uses granularity partially thin, abrasive material is thinner, and polishing scratch is smaller, vibration force is also got over
Small, the sharpness of grinding reduces.
With the development of modern industry, to the raising of the roughness of workpiece surface and flatness requirement, market competition is more
Fierceness, more perfect, enterprise more focuses on production efficiency, reduces production cost, and in order to solve these problems, market in urgent need is a kind of
Novel cymbal type resin wheel, can quickly polish workpiece and workpiece surface finish and planarization, while not have again
There is vibration, the comfort for keeping operation and using.
A kind of grinding wheel and preparation method thereof quickly polished for workpiece surface of CN105563355A, discloses a kind of sand
Wheel, the raw material including following weight parts: 20-30 parts of level-one Brown Alundum, level-one plate 15-20 parts of iridium white fused alumina, level-one single alundum
